Papaja – APA manuscripts made easy

Do you also find it time-consuming to make your manuscripts follow American Psychological Associations (APA) guidelines? Have you searched the internet for a good .docx/.doc APA template? After reading this post, you might not have to search anymore. Papaja is an r-package that makes your manuscript conform to APA guidelines! In this post, I am briefly going to describe the Papaja, how to use it to create APA manuscripts, and what I think of it.

Reverse Scoring using R Statistical Environment

This post is my first on R and it will describe a method on how to reverse scores using R.

Reverse scoring in R

Many instruments (i.e., questionnaires) contain items that are phrased so that a strong agreement indicates something negative (e.g., “When there is music in the room I find it hard to concentrate on reading”). These items need to be reversed so that the data will be correct later for statistical analysis.

For more information on reverse scoring, please see my earlier post: Reverse scoring in Python.  Since I was more  familiar with Python  compared to R, and I had no clue on how to do this in SPSS, I wrote a Python script. The Python script used a function that used Pandas DataFrame and it reversed the scores nicely and quickly.
